Particularly, the invention replaces the function of traditional hinge with the use of surface friction, thus significantly reducing the use of metal for cost down purpose. The preferred embodiments of the invention will be described in detail below, so as to well describe the features, the spirits, the advantages, and the easiness while actualizing of the invention.
Referring to
In an embodiment, a way for pivotally mounting the supporting member 16 to the first end 142 of the shelf member 14 is to assemble a shaft 166 and a screw 168. As shown in
In an embodiment, the base 12 has a second arc surface 124; the sliding member 18 has a second friction surface 184 which contacts the second arc surface 124. During rotation of the supporting member 16 relative to the shelf member 14, the second friction surface 184 of the sliding member 18 slides on the second arc surface 124.
In an embodiment, the base 12 thereon provides a groove 126 which is formed between the first arc surface 122 and the second arc surface 124. The sliding member 18 includes a protrusion 186 which extends toward to the base 12 and is limitedly movably disposed in the groove 126.
As shown in
Referring to
Besides, in the embodiment, it is notable that the resilient member 164 is compressed between the supporting member 16 and the sliding member 18. After the screw 165 passes through the aperture 1622 to rotate downward into the screw hole 183, and the head of the screw 165 contacts the aperture 1622, the motion of rotating of the screw 165 makes the sliding member 18 directly move upward along the thread of the screw 165, such that the compression of the resilient member 164 is increased. However, the frictional force that the sliding member 18 applies to the base 12 is decreased. In contrast, when the screw 165 rotates out of the screw hole 183, the sliding member 18 will directly move downward along the thread of the screw 165, such that the compression of the resilient member 164 is decreased. However, the frictional force that the sliding member 18 applies to the base 12 is increased.
As shown in

Similarly, in the embodiment, it is notable that the resilient member 264 is compressed between the supporting member 26 and the sliding member 28. After the screw 265 passes through the aperture 283 to rotate upward into the screw hole 2622, and the head of the screw 265 contacts the aperture 283, the motion of rotating of the screw 265 makes the sliding member 28 directly move upward along the thread of the screw 265, such that the compression of the resilient member 264 is increased. However, the frictional force that the sliding member 28 applies to the base 12 is decreased. In contrast, when the screw 265 rotates out of the screw hole 2622, the sliding member 28 will directly move downward along the thread of the screw 265, such that the compression of the resilient member 264 is decreased. However, the frictional force that the sliding member 28 applies to the base 12 is increased.

Furthermore, in an embodiment, in order to reduce the consumption of metal, the base 12, shelf member 14, the supporting member 16, and the sliding member 18 are formed of a polymer material. The sliding member 18 can be made of nylon, and the material of the base 12, the shelf member 14, and the supporting member 16 can be a specific thermal composite material, such as Acrylonitrile Butadiene Styrene Copolymer. Therefore, the consumption of metal can be significantly decreased to reduce the cost of manufacturing.
